What is the code P0128 on a 2014 Dodge Dart?

P0128 Code on a 2014 Dodge Dart
The P0128 code on a 2014 Dodge Dart indicates an issue with the engine coolant thermostat temperature being below the regulating temperature. This can lead to various symptoms and requires proper diagnosis and repair to resolve. Here’s a breakdown of the key points related to this code:
Symptoms of P0128:
– Check Engine Light is on
– Higher than normal idle
– Decreased fuel economy
– The temperature gauge is unusually low
Diagnosing and Fixing P0128:
The first step in addressing the P0128 code is to get it properly diagnosed to determine the cause of the malfunction in the coolant temperature circuit. Using the live data function of a diagnostic tool allows for the analysis of engine temperatures to diagnose the issue accurately. If not comfortable diagnosing this issue at home, it’s recommended to seek assistance from a RepairPal-certified shop to pinpoint the problem and provide an accurate estimate for repairs. These shops also offer a minimum 12-month, 12,000-mile warranty and guaranteed fair pricing.
Cost of Fixing P0128:
The cost to diagnose the P0128 code is typically 1.0 hour of labor, with auto repair shops charging between $75 and $150 per hour. The actual cost of repairs may vary depending on the location, make and model of the vehicle, and the engine type.
Causes of P0128:
The P0128 code is often caused by a leaking cooling system or a malfunctioning thermostat, which prevents the coolant from reaching the radiator until the engine reaches the right temperature. Other potential causes include a thermostat stuck open or issues with the Engine Coolant Temp Sensor.
Additional Information:
– There are technical service bulletins for several Jeep and Dodge models that recommend reprogramming the PCM (engine computer) if the code P0128 is diagnosed. Another TSB describes a problem where the thermostat may move out of place, allowing coolant to pass through and set the code P0128. The solution involves adding a shim and replacing the thermostat housing with an updated part.
It’s important to address the P0128 code promptly to prevent increased emissions and decreased fuel efficiency. If you encounter this issue, it’s advisable to seek professional assistance for proper diagnosis and repair.
